I have been trying to figure out why Office apps such as Excel, PPT, etc. randomly crash on me. The crash is simple, the interfaces stop responding to or displaying any changes in cells, fields, etc. I can still click, save and close... but visually it is non-responsive. After an increase in frequency over the past few days that coincided shortly after with a "Intel Display Driver Crashed" warning I think that these issues are caused by the driver... I thought this was fixed in December update? The Intel driver / adapter crashes for me 1-2x a day.
